-// fibo <n> compute fibonacci(n), n must be >= 0
-// fibo -bench benchmark fibonacci computation (takes about 1 min)

// Additional flags:
// -half add values using two half-digit additions
-// -opt optimize memory allocation through reuse
-// -short only print the first 10 digits of very large fibonacci numbers
